Global Systems

Climate change, air quality, infectious diseases, and oceans. None of those issues are limited to one country, or continent, they affect multiple countries, and are controlled by global dynamics. Global systems span wide in reach in terms of spatial scale and impact, and encompass connections between small and large. We focus on issues impacting the entire globe and associated natural and human-made systems.

Aerosols are a major component of air pollution. They alter the climate, impact ecosystem health, and lead to over 3 million premature deaths per year world-wide. Professor Heald’s group develops models that describe how these particles are produced.

Modeling the Aerosols in our Atmosphere

Aerosols are a major component of air pollution. They alter the climate, impact ecosystem health, and lead to over 3 million premature deaths per year world-wide. Professor Heald’s group develops models that describe how these particles are produced. View a short video produced by CEE postdoc David Ridley depicting a GEOS-Chem Global Aerosol Model Simulation.

Retail is fast evolving into a complex multi-channel highly competitive environment. Companies are relying on a combination of accessible data, ability to experiment and analytic technologies to enable a new approach to various processes such as inventory management and pricing. Professor Simchi-Levi’s breakthrough research develops algorithms that combine machine learning and optimization for pricing that significantly improve revenue and reduce inventory risks. These algorithms have been implemented in online retailers like Rue La La, Groupon, and a large online retailer in the Americas with significant impact on revenue, profit and market share. For example, Rue La La reported a 10 percent improvement in revenue.

The project investigates a risk modeling and data analytics platform that identifies risk tolerance and strategy for assessing, responding to, and monitoring cyber security risks on a simulation platform. The simulation will act as a proxy to the physical infrastructure.
